Chronic Obstructive Pulmonary Disease (COPD)

#COPD, #chronic obstructive pulmonary disease, #airway obstruction, #smoking, #pulmonary function test, #bronchodilator, #smoking cessation, #emphysema, #dry cough, #persistent minor cough, #cough that will not stop

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease in which the airways (the passages through which air travels) gradually narrow, making breathing difficult. The leading cause is smoking. Airways that have narrowed are mostly not restored, so early detection and smoking cessation are especially important. If cough, sputum, or shortness of breath persists, please consult a pulmonology and allergy specialist.

Early Detection and Management of Liver Disease

#liver disease, #liver cancer, #cirrhosis, #hepatitis B, #hepatitis C, #fatty liver, #nonalcoholic steatohepatitis, #hepatectomy, #minimally invasive surgery, #early screening, #alcohol abstinence, #lack of energy, #listlessness, #persistent tiredness, #nausea, #feeling about to vomit, #vomiting

The liver is a 'silent organ.' Even as damage progresses, there are no obvious symptoms in the early stage, so fatigue, loss of appetite, and weight loss are often dismissed as minor, and the disease is often discovered only after it has progressed to cirrhosis or liver cancer. Regular checkups are the most important way to protect liver health.
